I've used mono on the desktop and subjectively compared it to Java.

As a runtime mono seems usable on a "low powered" cpu (e.g. 450mhz) and memory consumption seems lower compared to Java.

I just wondered how usable this "arm" version of mono is on your n810.

You know - maybe I shloud just install it myself and try it myself.

It's great there is another programming option for maemo. It would be nice to develop stuff for mono and then use the same binary on n900 & n8x0 devices.
